AIS traffic comes from a radio receiver via a serial link most generally. Could be integrated using a Bluetooth stream as well. As I understand it class A traffic (the big ships), transmit position twice a minute and generally are moving @ 5 to 25 knots. Class B traffic (us little guys), are transmitting once a minute and could be at 6 knots for the rag driven and 35+ knots for the stink pots. Guess I would recast the incoming traffic from AIS into the existing GPSDrive format as data off the friends server and have a look. US govt has finally adopted the Class B standard (better late than never) and receivers are on the market from $189 and up.<div>

Now if gdal support for wms is working up to snuff, we may have a very cool<br>
solution.<br>
